The Brauerei Päffgen is a great place to enjoy excellent Kölsch beer and great traditional German pub food. The heated beer garden is the perfect place to soak up all of the colognian culture, giving you the possibility to mix and mingle among the locals. This brewery makes their own beer, and it is rumored to be the best in all of Cologne, so it is definitely worth a try!
The prices are great (only 1.50€!), giving you a lot of delicious food and tasty beer for a fair fee.
